Be itknown that4 we, WILLET THOMPSON and JOSEPH A. GEORGE, of Brookiyn, 1in the y act description..` l l 1 y f `This invention consists, principally, of a hatf` pouncing `machine provided with a special u county of KingsandState yof NewYork, have invented a new and useful Improvement in Combined Hat-.Bouncing Machines and Lathes,

`f whichlthe following isa full, clear, and eX- `form of counter-balance, to prevent the swaya high rate of spced,and in providing Vthe machine withmeans for shifting'theposition of 1 ing or lurching movement ofthe machine, usu-` ally caused by the irregular'imovement `of the block, thus enabling the machine to" be run at theijstillpoint,"7 thus adapting the machine tobe used also forturning hat-blocks and other 'irregularforms ,s f s i The inventionconsists, also. of anew form of i chuck for holding the hat block or blocks to `be turned, and also ofthe constructiomar- A rangement, and combination of parts, all as i hereinafter described and claimed.

Reference is to behad to the accompanying -clrawings, forming part of this specification, in which similar letters of reference indicate corresponding part-s in all the figures.

l Figure l is a plan view of our improved hatpouncing machine and lathe. Fig. 2 is a sectional side clcvation of the same, showing a hat-block held bythe chuck. Fig. 3is afront elevation ofthe machine. Fig. 4 is a transverse sectionalelevation on the lineartn of Fig.

chuck D removed. Fig. 6 shows the shiftingV collar removed. Fig. 7 is a front elevation of the counterbalancing-plate. removed, and Fig. 8 is a front elevation of the hat-block E.

A represents the frame ofthe machine, which framecomprises the base a and uprights a a2.

In the circular Opening b, made through the upright a, is fitted the collar B. The main shaft Cof the machine takes its bearing at its forward end inthe collar B, and at its rear end in the journal b', made in the upright a The collar B has formed` integral with it, or has attached rigidly to it, the opposite eccentrics B B2, which serve to impart, through mechanism "hereinafter described., the desired irregular rotary motion to the chuck-D and i l hat-block E or other` object attached thereto,

and a like but opposite irregular motion also i or thereabout in the circular openingJ), by.; passing a rod down through slot c, made inthe `,to the counterbalancing-disklF, and the collar B `is adapted to .be given a onequarter turn,

upper edge of the uprightainto orificelc, for` shifting the so-called i. still-point 7--7-the `6e? y point where the surface of the blockE runs i true-,from a position nearlyover the shaft C,

whereit is most` convenient to apply/the sand-` u i 1 paper for pouncing a hat-body on the block E,to a position at the side of the shaft C, where `for turning a block held in the chuck'D.

u Upon the eccentric B is itted the plate G; il

165 it is most convenient` to apply a cutting-too1 i C i which is formed with the eccentric y, surrounding the eccentric B. The back of this plate-G comes flat against the front surface of theup-` right az of the frame of the machine, as shown` clearly in Fig. 2, and the plate G isjformed `with the curved slot g', through whichthe setscrew g2 passes, for holding the plate G at any desired position. By loosening the set-screw g2 the plate G may be adjusted-turned'backl ward or forward upon the eccentric B for increasing Or diminishing the irregular motion `imparted to the chuck D and block E.

Upon the eccentric g of the plate G is fitted the yoke H, whichhas the orifice h formed'in one end thereof.

The forward end of the main shaft C is screwthreaded, as shown at d, and upon this screwthreaded portion is screwed the plate Lwhich is formedwith the slots e e, and turns at all times with the shaft C as a part of it.

To the front surface of the plate Iare secured i the flanged plates J J, between the adjacent edges of which the face-plate K-is held. The plate K has formed upon its rear surface the blockf, which fits in the slot e of the plate or disk I, and the plate K is also furnished at the back with the block f', whiclits in the slot e of the said plate I, and this block f is formed with the pin ,which reaches past the rear surface of the plate I and enters the orifice h, made in the yoke `H,`las shown clearly in Fig. 2, so

that since the plate I revolves vwith the shaft IOO - the yoke H, and the yoke in turn imparts an irregular endwise motion to the face-plate K, the slots c c and the flange-plates J J permitting such endwise movement. The chuck D is attached rigidly to the plate K by the screwthreaded sh ank 7c of the chuck, which is screwed into the internally-screw-threaded collar lc', formed upon the front surfaceof the plate K, so that the chuck D and block E, held thereon,

` are given a rotary irregular motion, precisely similar to the motion imparted to the plate K. The irregular rotary motion of the plate K, chuck D, and block E, when the machine is run ata high speed, tend to cause a swaying or lurching movement of the `shaft C, and all of the other parts of the machine; but this Vlurching movement is prevented by the abovementioned counterbalancing-plate F, which has an irregular rotary movement the reverse of that of the face-plate K. The irregular motion of the plate F, as above mentioned, is

obtained from the eccentric B2, formed upon the rear surface of the collar B, which eccentric is the opposite of the eccentric B', and has fitted upon it the plate L, which' is formed withV the eccentric Z, (the opposite of the eccentric g 0t`plate-G,) surrounding the eccentric B. The back of the plateL comes-flat against the rear surface of the upright a2 'of the frame of the machine, and is formed with the curved slot Z', through which the set-screw Z2 passes, for securing the plate L at any desired position. By loosening the set-screw Z2, the plate L may be adjusted for increasing or diminishing the irregular motion imparted t0 the counterbalancing-plate F.

Upon the eccentric Z of plate L is fitted the the yoke M, which has the oriiice m formed in it, in which iits the pin m', formed upon the front surface of the counterbalancing-plate F, so that by this pin and orifice the said counterbalancing-plate F and yoke M are locked t0- gether. The'counterbalancing-plate F has the central slot, o, formed in it, through which the shaft C passes, and which permits the plate to have its irregular movement.

Upon the reansurface of the counterbalancing-plate Fare formed, just beyond the ends of the slot o and in line with the said slot,the blocks pp, which enter and t nicely in the slots q g, made in the cross-piece N, riveted fast to the hub r of the fly-wheel O, which is made fast to the shaft C, so that as the shaftis revolved the iiy-wheel and cross-piece N will be revolved with it. The latter being connected to the counterbalancing-plate F by the blocks p p, entering slots q q in the cross-piece, the counterbalancing-plate F will be revolved, and this plate being connected to the yoke M by pin m',

entering orifice m in the yoke, theyoke will be revolved, and its revolution being upon and around the eccentric Z, vit will receive a positive irregular movement from the eccentric,

`which will be imparted through pin m t0 the plate F, the slot o in the plate and the slots q q in the cross-piece N permitting such irregular movement. The eccentrics Z and B2 being opposite to the eccentrics B and g, which impart irregular motion to the plate K, it follows that the irregular movement of the counterbalancing-plate F will be exactly the opposite of the irregular movement of the faceplate K, and that the plate F will thus offset the tendency of the plate K to cause a lurching or swaying movement of the machine. The chuck D is composed of the head d and arms Z2 d3, pivoted to the said head.v The head cZ is`formed with the above-mentioned screwshank 7c, by which the chuck is attached to the plate K, and beneath the, pivots of the arms (Z2 d3 the head d is recessed, as shown at s s, Fig. 3, and in these recesses are placed the coiled springs t, which act upon the arms Z3 in front of their pivots, so as to tendto force their outer ends outward or away from each other. l The arms d? are each provided at their outer ends with apivoted plate, u, pressedV inward at its rear end by the spring u', and at their rear ends with the pivoted plates c, .which are adapted to rest upon the outer edge of the cam P. The arm (Z3 has pivoted to its outer end the plate u2, which is formed with the viin ai and acted upon by the springs u', and provided at its inner end with.

in the said collar, as shown in Fig. 2, so that by loosening the said set-screw the cam may be turned upon the collar j as an axis. The block E is formed with the openings E', as shown in Fig. 2, to receive the forward ends of the arms d2 d3 and plates u u2, attached to them, and the block is formed with a groove to receive the iin u of the plate u2, so that the block may always be placed in the chuck in the proper position. The blockE being placed upon the arms d2 cl3, a wrench will be applied to the set-screw j to loosen the' cam P on collarj; then the cam will be turned in the direction indicated by the arrow in Fig. 3, which will force therrear ends of the arms d2 d3 outward, causing the forward ends of the arms and platesu u2 thereof to grasp and firmly hold the block E. The set-screw j will then be turned inward for holding the camP in place. The opposite movement of the cam P upon the collar j will cause the arms Z2 d3 t-o release the block E. The plates o and at being pivoted to the arms Z2 d3 serve to always effect a true bearing of the said arms upon the edge of the AcainP, and the said plates u and u2,being pivoted, accommodate themselves to the recesses in the block, and also to the IOO IIO

inclined position which the arms d2 di assume While holding the block, so `that a iirm and stillpoint nearly over the shaft C, Where `the attendant can apply the sand-paper to the hatbody With .the greatest ease.

When the machine is to be used for turning, `the collar B Will be turned in the open ing b so that the recess c Will stand to one side of the shaft C, which will again shift the eccentric B', and bring the still-point, nearly in the same horizontal plane with the shaft C, Where it is most convenient to apply the cutting-tool. i

In turning the collar Bit will be seen that both eccentrics B B2 will be shifted in opposite directions, so that Whatever change is thereby given to the irregular movement of the yoke H and plate K and the parts attached thereto a like opposite change will be given by the movement of the eccentric B2 to the yoke M and counterbalancingplate F, so

that the plate F Will always fperfectly counterbalance the machine, so that the parts cannot possibly get'out of balance.`

Having thus fully described our invention, we` claim as new and desire to secure by Letters Patenty l. The plate K, arranged to receive irregular rotary movement from the eccentric B', in

combination With the counterbalancingplate F, arranged to receive opposite irregular movement from the eccentric B?, the eccentrics B B2 being adapted to be turned for shifting the still-point, substantially as and for the purposes described.
